BREECH-LOADING MECHANISM.

Specification of Letters Patent.

Patented July 30, 1907'.

Application filed June 11,1906. Serial No. 321,164.

To all whom it may concern;

Be it known that I, .intrus Brianna, residing at Milwaukee, I\\\"iseonsin, have invented a Breeeh-Leading pin b thereby permitting said lever to slide longitudi- Mechanism, of which the following is aspeciiication.

The object of this invention is to produce a novel and improved breech-loading mechanism designed more particularly for shot-guns.

My improved construction is fully illustrated in the accompanying drawings in which.

Figure l is a fragmentary longitudinal section of a breech mechanism according to my invention` showing the operating mechanism in elevation and the action closed. Fig. 2 is an enlarged longitudinal section iu the same plane as Fig. l showing the action open and the breech-block in section at one side of its center. Fig. 3 is a view similar to Fig. 2 but with parts removed and showing the breech block in central i section. Fig. i is a fragmentary central horizontal section through the breech of the gun, with parts removed. Fig. 5 is an enlarged fragmentary view of the receiver, showing the magazine-stop in elevation. Fig. 6 'is a fragmentary perspective view of the fingerlever operating the breech mechanism. Fig. 7 is a perspective view of the shell carrier.

The frame or stock A carries the barrel a. having shown as ing inwardly between the locking bolts is the finger lever C which, as shown, at its point of support is provided with an elongated slot to receive said bolt or nally on said pin when operated. Said lever is provided at its outer end with an operating handle c as is usual in such constructions and the inner end Vc/ thereof extends upwardly and forwardly and is provided with rounded apertured lugs cl--cge the former of which is integral with said lever and the latter of which is secured thereto, laterally thereof, by a block c4 and is spaced a distance therefrom as is shown more clearly in Fig. l0. Said lugs cl-c3 are rounded thereby affording cam surfaces and at their rear sides are provided with abrupt shoulders c. Said breech block as shown more clearly in Figs. 2 and 9 is recessed on its under side to provide downwardly opening recesses which are separated by a central web a5 and in which the lugs c2 and c3 on the iinger lever project and are secured therein by means of a pivot pin c extending transversely therethrough and through the breech block.

The magazine a/ is provided with a spring controlled follower (L7 by means of which the shells are moved into the receiver, as is usual in such devices and rigidly engaged on the side of the receiver and extending forwardly and inwardly is a leal` spring aS which normally projects in iront of the magazine as shown more clearly in Fig. 4, and is provided on its forward thereof .near the top with longitudinal grooves or ways i rectangular in cross section and provided en the sides .thereof with longitudinal ribs a'l-ar adapted to slide in said grooves (13. Slidably engaged in vertical grooves in the walls of said receiver are the locking bolts B which as shown are rigidly connected at their lower ends by a transverse bolt or pin b. When the action is closed as shown in Fig. l the locking bolts B extend upwardly, flush with the top of the breech block A/ which, as shown, is provided in each side with a vertical groove to receive said bolts B when the block is at the forward limit of its movement thereby locking said block against rearward movement until said belts are retracted. A locking bar l'/ is pivoted at its forward end on a pin b. secured in the wall of the receiver and the rear end thereof is mov-ably engaged in a recess in the adjacent locking bolt I3 thereby permitting said bolt to travel vertically and carry the end of the bar tlnfrtavith. A lug or slop bl on the wall of the receiver limits the downward movement of said bar but permits the locking bolt to move downwardly a sufficient distanee to release the breech block.

Pivotally supported on the bolt or pin b and extendend with a beveled stop block a adapted to engage against the shells A2 and prevent them from being projected into the receiver when the action is open.

The carrier D comprises as shown two parallel bars d and df which are integrally connected at their forward ends and are provided with upwardly and outwardly directed lugs or stops d2 against which the head of the shell abuts when forced into the receiver from the magazine. Said bar df as shown is provided with a longil tudinal slot d3 which curves upwardly at its rear end and at the rear end of said bar is an integral extension or arm d'1 which extends rearwardly between the bolts B-B and is pivoted upon the transverse pivot bolt or pin d5 which is rigidly engaged in the walls of the receiver rearwardly of said locking bolts B. A downwardly and forwardly curved arm or link D is pivoted at its upper end to the inner end of the finger lever by means of a pivot pin or stud d extending through said lever and at its lower or forward end is provided with a pin or stud (Z7 which is slidably engaged in the slot cl3 of the carrier and when said 'finger lever is operated to close the action said link D/ moves to the forward end of said slot and forces the forward end of said cai'- rier downwardly beneath the mouth of the magazine to the position shown in Fig. l. Owing to sliding engagement of said linl; with the carrier the latter may be depressed in filling the magazine without moving the breech block forwardly. The forward end D8 of the carrier D is beveled downwardly to engage the stop block a9 and force it laterally thus permitting a shell to be forced rearwardly into the receiver from the magazine onto the carrier D and into engagement with a shoulder c7 on the forward end of the finger lever as shown more clearly in Fig. l. As shown the finger lever C is provided above the pivotal point with shoulders cS-cS upon which the carrier rests when the action is closed thereby limiting the downward movement of said carrier.

A push bar D2 is pivoted at its forward end to the forward end of the carrier and extends rearwardly and downwardly beneath the same and a push spring D3 is engaged at one end on the rear end of said bar and at its other end is seated in a suitable seat in the forward side of the finger lever slightly below its pivotal point and acts when the gun is thrown into open action to force the forward end of said carrier upwardly but when the action is closed acts to hold the lever' from operation, thereby preventing downward movement of the locking bolts. l

Near the rear end of the extension or arm d4 is provided an integral, transversely directed lug or stop dQ which extends into the path of movement of the end c of the finger lever C and acts to limit the rearward movement of said lever thereby preventing the for- Ward end of the carrier being thrown into too high a position for the shell to enter the gun barrel.

The breech block A is provided in the top thereof with a resilient retractor E which may be of the usual or any preferred construction and adapted to engage over the head of the shell and withdraw the same from the barrel after discharge and as shown, a firing pin F is slidably engaged in a longitudinal bore in said breech block and adjacent the lugs c2 and c3 of the finger levelI is reduced in thickness to pass between said lugs. Said pin is cut away on its under side to permit the same to pass over the pivot pin cG -connecting said finger lever with the breech block and is provided with a` contact point f adapted to contact with the cap of the shell as is usual in such devices. Near the rear end of said reduced portions of the firing pin are the forwardly and downwardly beveled shoulders f against which the lugs c2 and c3 of the finger lever engage when the action is open to hold the iii-ing pin retracted but which when the action is closed may enter beneath the shoulders c5 on said lever in discharging the gun.

The breech block as shown is provided in its forward end beneath the ring pin with a chamber in which is slidably engaged the ejector F which, as shown, comprises a head f2 which when the breech block is retracted, rests against the upwardly directed lugs f3 integral with and'extending forwardly a slight distance from the front face of said breech block and limiting the outer movement of said head beneath the pivot pin c6 and a coiled spring f5 is carried thereon and engages at one end against said head and at the other end against the finger lever and actsnormally to hold said ejector at its outer limit of movement as shown more clearly in Figs. 2 and 3.

A hammer G of any desired construction is pivoted on the pin d5 and is adapted to be cocked by the rearward action of the breech block in the usual manner. Said hammer as shown is provided on its lower end with a rearwardly directed lug g on which is pivoted a link bar g the upper end of which is engaged by the main spring G which is rigidly secured at its rear end in the stock in any desired manner and which acts normally to force said hammer forwardly. Said hammer is provided on its lower end with notches or teeth g2 adapted to receive the nose g3 of the trigger G2 which as shown is pivoted on the stock adjacent the hammer and a spring g4 also carried on said stock engages at its Yforward end a lug g5 on -said trigger and acts to hold said nose in engagement with said teeth g2 when the gun is cocked` As shown, lugs y extend upwardly from the rear wall of the receiver and are apertured to receive the pivot pin d5 and act as guides to center the hammer. Extending downwardly and forwardly from said lugs are the arms g7 which act to impinge against the iinger lever C and to hold it from movement when the action is closed. I

In a breech1oading magazine gun, the combination of a 'carrier pivoted at its rear end and adapted to receive cartridges from the magazine and raise them to the barrel of the gun, a inger-lever having a pivotal movement in a vertical plane and adapted by its movement to open the lock and raise said carriery a push-bar pivoted to the forward end of said carrier, and a compression-spring connecting vthe rear end of said bar to said linger-lever close to and slightly below the pivot of said finger-lever when the latter is closed, whereby said spring acts to hold the fingerlever in closed position and to raise said carrier when released by the opening movement of said nger-lever.

In testimony whereof I have hereunto subscribed my naine inthe presence of two subscribing witnesses.
